Application filed May 2,

To all whom it may concern:

Be it known that we, WILLIAM L. BRALEY and HENRY N. FAAs, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Im rovements in Cultivators, of which the ollowing 1s a specification.

Our invention relates to improvements in cultivators, it particularly relating to cultivators of the two row type.

' One of the objects of our invention 1s to provide improved means for shifting the beams and wheels to follow the corn rows, a further object in this connection being to provide shifting mechanism which will also act to brace the draft bar against the strain of draft of the cultivator beams.

A. further object of the invention is to provide an improved manner of connecting the wheel spindles to the draft bar to cause the 'wheels to be turned with the beams, said connections furnishing a means for bracing said bar against the strain of draft.

A further object of the invention is to provide an improved method of adjusting the beams for different widths of corn rows; amore specific; object in this connection being to provide a scale at a convenient pomt with relation to the beams by which the operator may readily set the beams for different widths of corn rows and also to cause the shovels tocultivate at the proper distance from the rows.

In the accompanying drawings:

Fig. 1 is a rear view in perspective of a cultivator embodying the improvements.

Fig. 2 is a partial plan View of the same.

Fig. 3 is a side elevation of a portion of the machine.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is a front elevation of a portion of the machine.

In the said drawings, 1 represents the front rail and 2 the rear rail of the main frame, these rails being connected by cross-pieces 3, 4, 5 and 6. In this machine the draft appliances are connected with the main frame, a portion only d being shown in Fig. 2. The draft bar is shown at 7, being supported from the front rail 1, which is preferably of angle iron construction by three hangers 8, 9 and 10. Each of these hangers is in the form of a yoke, the arms of which I 1923. Serial No. 636,122.

carry a roller 11 which rides'upon the top surface of the front rail 1, the lower portion of the yoke being apertured to receive the draft bar 7 which is fixedly secured therein by a set screw 12. The beams 13 are pivotally connected at their forward ends to bifurcated heads 14, mounted upon the draft bar 7 and held against lateral movement thereon by collars 15' secured. to the draft bar by set screws 15.

For the purpose of enabling the operator to readily set the heads 1 1 at the proper point on the draft bar in order toadjust the beams and their shovels to correspond to the different widths of corn rows, we pro vide on the forward side of the front rail 1 two scales marked with numerals which indicate the distance between the corn rows. As anexample, if the rows of corn are forty inches apart and the operator wishes tocultivate within eight inches of the corn, then each of the heads on the left-hand'side of the machine will'be set eight inches on each side of the numeral 40 on that side of the frame and the heads on the right-hand side of the machine likewise adjusted with respect to the numeral 40 on the right-hand of the machine.

Each of the carrying wheels 16 is journaled' in the usual wayupon the horizontal 85 portion 17 of a spindle, the vertical portion 18 of whichis journaled in a sleeve 19 clamped to the vertical portion of an L- shaped arm- 20, the horizontal portion of which is secured to the rear rail 2. Heretofore it has been usual to connect the spindles to the draft bar by loose links, but in the present case we have formed the spindles with integral forwardly extending ,arms 21 which are pivotally secured to the respective hangers 8 and 10 by the bolts 22, the hangers being provided with cars 23 for the purpose. In order to adjust the distance between the carrying wheels 16, the horizontal portions of the arms 20 are adjustably secured to the rail 2 and to that end the arms and rail are provided with a series of perforations 24 which receive the bolts 25 so that the arms can be moved in or out relatively to the rail. When an adjustment is made of this character the hangers 8 and 10 are likewise adjusted on the draft bar 7 by positioning the set screws 12 which connect the hangers to the draft bar in the proper recess 26 in the bar.

To give the necessary-endwise movement 110 to the draft bar 7 to guide the-v machine to cause the shovels to follow the corn rows there is pivotally connected to the middle hanger 9 a longitudinally-arranged bar 28 which is pivotally connected by the bolt 29. to the central portion of the rail 2. A pair of foot levers are pivotally connected to,

brackets 31 on the rail 2 with their short arms connected to the barf-28' by thelinks 32, Depression of one foot lever shifts the clevicesaiin one direction and depnession of the other: foot lever shifts the devices in the opposite direction.

It will be notihcd that. the fiiblih ban :1 isextcnded at the ends, as indicated at i so. as toiprovide a support for the hangens 8 and 10s The draft and: weight of the beams: is oiiconrse supported by the front rail 1 and by having thefrontbar 1 extended as shown: so as to provide a support for the side' hangers which may be positionech in, line with the spindle extensicn ElIlSQIlZL-lilCSiUS to employ these spindle extensions to cooperate withthebar 28: to act as braces against the strain of draft.
